Claims
- 1. A stain-resistant printed nylon carpet composed of cationic-dyeable fibers printed at a pH of from about 2.0 to about 6.5 with an acid dye or a premetallized acid dye print paste and overprinted at a pH of from about 2.0 to about 6.5 with an acid dye or premetallized acid dye.
- 2. A stain-resistant printed nylon carpet composed of cationic-dyeable nylon and printed at a pH of from about 2.0 to about 6.5 to a predetermined depth of shade with an acid dye print paste and overprinted with an acid dye or a premetallized acid dye.
- 3. A stain-resistant nylon carpet composed of multicolored heatset cationic-dyeable fibers printed at a pH of from about 2.0 to less than about 6.5 with an acid dye and having the apparent stain resistance and fastness to light of acid dyeable nylon dyed to the corresponding shade.
- 4. A stain-resistant nylon carpet composed of multicolored heatset cationic-dyeable nylon and printed at a pH of from about 2.0 to less than about 6.5 to a predetermined depth of shade with an acid dye, the carpet being resistant to acid type stains and exhibiting improved fastness to light as compared to cationic-dyeable nylon dyed to a similar depth of shade with a cationic dye.
- 5. A stain-resistant nylon carpet composed of multicolored heatset cationic-dyeable fibers printed at a pH of from about 2.0 to less than about 6.5 with a premetallized acid dye.
- 6. A stain-resistant nylon carpet composed of multicolored heatset cationic-dyeable nylon and printed at a pH of from about 2.0 to about 6.5 to a predetermined depth of shade with a premetallized acid dye.
